Be it known` that Lui/terr D, Hunnnnn, a citizen ot the 1[vlnited S Y, yTUtica7 in the county ot Oneida andtate ol'lilew York, has invented nenTand useful improvements in Hot Plategvof which the following' isaspeciiication.`

rthis invention relates to hot-plates `for ranges and proposes theconstructionoif a siniple'and inexpensive device for supportingv a cootiutensil upon a gas range and which adapted to admit-and enclose theflame chamber on the underside of the hotplate at points remotefrom thellame opening', tov permit theiame to be drawn into said chamber.y

A further'object of the invention is the construction oft a hot-platehaving an upper iinpe-riforate wall ot sheet metal serving as a supportfor a. cooking vessel and .being secured in spaced relation to a'lowerwall, enclosino' with said wall a lame'chamber, said lowerpwall beingprovided with a central openinnf and withV a plurality of spacing lugscontacting' with said upper wall and arranged around said centralopening, being separated to afford communication between said opening'and said flame chamber.

`For a full understanding voit the invention and the merits thereof andalso to acquirea knowledge of the details of construction reference isto be hadvto the following;` description and accompanying drawings, inwhich Figure Vl is a perspective view of my improved hot-plate, aportion thereof being broken away.V Y

VFigure 2 is a plan view of the blank from which the lower portion ofthe hot-plate is stamped up.

Figure 3 is across section taken diametri.-

ites, residing' at 5, 1922. Serial` No. 586,359.

cally through the hot-plate shown in Figure l.l j Y Referring now indetail to the several 15g;- ures, the numerai l represents the vupperwall oi' thehot-plate which is 'termed from a plane iniperforatecircular blanl; having' a flange Qthereof struck down at right angleskto the main portion ot the blank ias shown in Figure Thispart oi thehot-plate is telcscoped over the upturned flange 2 of the lower wall.the latter being formed 'from a similar althoughslightly suiallerblankto that 'tromiwl'lich the upper Vall'V is stainpefgl. and having' itsperipheral edn'e upturned to `torni the flange This blank is shown inFigure 2 and it will be observed that a central openingijjf is stampedout, likewise a circular series of apertures 5. the latter being'arranbqjedat points remote trein the central opening' 1- V A pluralityof spaced lues` G are formed on the peripheral edge ot' the.

opening` 4 and are struck up at rifgght angles as shown in Figure lltoform spacing' elements which Contact with the upper wall l reinforcingthe central portion thereoil so as to prevent collapse of the same whenit is carrying a cooking` utensil. The upper and lower walls oit thehot-plate enclose an annular flame chamber 7, and the lugs 6 are spacedapart so that thecentral opening' 4: affords communication between saidopening and said chamber for the passage into the latter et a iiameentering the opening 4. The tlangres 2 and 3 ot the upper and lowerwalls respectively are secured together as shown at 8by turning' thelower edge of the flange 2` which is made slightly longer than theflange 3, inwardly over the latter.

In opera-tion, the hot-plate is placed over the burner of a range orstove and the cooking vessel placed on top of it.Y The iiame Atrom theburner enters the opening' 4L and plays within the flange chamber 7. Thevent apertures 5 permit the escape of the products of combustion andproduce a draft which ensures the drawing of the fiame into the flamechamber. All of the heat of the anie is confined to said flame chamberand to the walls thereof, none of it beine' dissipated into the air andup around the sides of the cooking utensil. The same amount of availableheat may be obtained by using` my improved hot-plates with a smallerflame than is possible without said lli4 hot-plate, thus effecting asubstantialv eeononly Vin the amount olz gas-eoneuined. Furthen-more7the sides et the cooking' vessel a re protected from being blackened oroverheated by the products ot combustion, and the handles of saidvessels remain cool.

While l have shown in the preferred ein'- bodinient illustratedv in the.present drawings a torni of construction oli' my improved hot-platewhich. is extremely simple and in ixpensive to manufacture yet is withinthe spirit of the .invention to adopt 'such .l'iang'es 'iu structure,and variatiens in the details oi the several l xetui-es as ie permittedbythe scope of the claiins.
